             Summary: smokeTestRelease.py's regex for TestBackwardsCompatibility is brittle, breaks if user uses ant's ANT_ARGS
                 Key: LUCENE-6235
                 URL: https://issues.apache.org/jira/browse/LUCENE-6235
             Project: Lucene - Core
          Issue Type: Bug
            Reporter: Hoss Man


smokeTestRelease.py has always exec'ed "ant" on source releases to smoke check the build - but the changes intorduced in LUCENE-5863 also do a regex over the output of the ant call to run TestBackwardsCompatibility.

This regex doesn't play nicely however if the user has ANT_ARGS configured to use an alternative logger - in particular i (and i'm guessing i'm not alone among the general ant using populace) have this in my shell...

{noformat}
$ env | grep ANT
ANT_HOME=/opt/ant/default/
ANT_ARGS=-logger org.apache.tools.ant.listener.AnsiColorLogger
{noformat}

The AnsiColorLogger, and the control characters it outputs to color the output lines, seems to break the regex matching for TestBackwardsCompatibility's output.

Workarround (seems to be - still testing) for smoke testers to force their environment to specify the DefaultLogger...

{noformat}
$ ANT_ARGS='-logger org.apache.tools.ant.DefaultLogger' python3.2 dev-tools/scripts/smokeTestRelease.py http://people.apache.org/~anshum/staging_area/lucene-solr-5.0.0-RC2-rev1658469
